I can think of three reasons I use Amazon's store beyond the free apps: 1. It's a great way to share paid apps within a household without sharing Google accounts. 2. We have one device (a kids' tablet) that didn't come with and still doesn't have Google Play. Even Amazon's store is light years ahead of the one that came pre-installed. 3. Exclusives. For me that's Instant Video, but I believe other people also care about the temporary third-party exclusives (usually games). This reason often provokes annoyance and grumbling because it feels arbitrary and unnecessary, but it is still a reason nevertheless.
